模拟多人徒步爬山，使用多线程模拟多人徒步爬山训练要点，使用任意一种方式创建线程，使用 Thread.sleep()方法设置线程休眠。需求说明：每个线程代表一个人可设置每人爬山速度每爬完 100 米显示信息爬到终点时给出相应提示。

代码：
MyRunnablethree.java

package duo2;

public class MyRunnablethree extends Thread{

private int time; public int num=0;

public MyRunnablethree(String name, int time,int kio) {

super(name); this.time = time; this.num=kio*1000/100;

}

@Override public void run() {

while (num>0){ try {

Thread.sleep(this.time);

} catch (InterruptedException e) {

e.printStackTrace();

}

System.out.println(Thread.currentThread().getName()+"爬完 100 米！");

num--;

}

System.out.println(Thread.currentThread().getName()+"到达终点！");

}

}

Test1.java

package duo2;

public class Test1 {

public static void main(String[] args) {

MyRunnablethree aged=new MyRunnablethree("老年人",1500,1);

MyRunnablethree youngPeopl=new MyRunnablethree("年轻人",500,1);

System.out.println("********开始爬山********");

aged.start(); youngPeopl.start();

}

}

效果如图:
